[0003] 2. Description of the Prior Art

[0004] For the present, electric scooters are very popular. In fact, the electric scooters have good sales in the market when they are firstly introduced to the customers not only because they do not produce exhaust to pollute the air, but also because the compact design of their structure is suitable for people of different ages to ride. Although the electric scooters can bear weight about 100 kegs, most conventional electric scooters are made integral with handles and seats mounted at a fixed position, which is very inconvenient and uncomfortably for high people to ride because their fixed handles and seats greatly limit the movements of high people's hands and legs.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[0018] A preferred embodiment of a height-adjusting device for a handle and a seat of an electric scooter in the present invention, as shown in FIGS. 1 to 4, mainly includes a handle tube 22, a handle stem 30, a seat tube 51 and a seat post 60.

[0019] An electric scooter 1 is composed of a front frame 2, a handle 3, a footrest 4, a rear frame 5, a seat 6 and an electric motor 7. The front frame 2 disposed at a front of the electric scooter 1 has a front wheel 20 pivoted at a lower portion thereof and two front shock absorbers 21 respectively mounted at both sides thereof. The handle 3 is mounted on the front frame 2. The footrest 4 is disposed between the front frame 2 and a rear frame 5. The rear frame 5 disposed at a rear portion of the electric scooter 1 has a rear wheel 50 pivoted at a rear end thereof and two rear shock absorbers 53 respectively mounted at both sides thereof. The seat 6 is mounted on the rear frame 5. The electric motor 7 is mounted on a front portion of the rear frame 5 and connected with the rear wheel 50 by a belt for driving the rear wheel 50 to rotate.

[0020] The handle tube 22 extended upwards from the front frame 2 of the electric scooter 1 has two projections 220 respectively disposed at two opposite sides of a top end of an inner surface of a wall thereof, and a plurality of engagement holes 221 vertically arranged in the wall thereof. A clamp member 23 mounted to the top end of the handle tube 22 has a screw member 24 capable of extending through a front side of a wall of the clamp member 23 and a front side of the wall of the handle tube 22 so as to screw the clamp member 23 and the handle tube 22 tightly.

[0021] The handle stem 30 extended downwards from the handle 3 of the electric scooter 1 is capable of being inserted and engaged in the handle tube 22 of the front frame 2. The handle stem 30 has three grooves 300 respectively disposed at both sides and a front side of an outer surface of a wall thereof for corresponding in position to the two projections 220 of the handle tube 22 and the screw member 24 of the clamp member 23. A resilient stopper 301 is accommodated in an interior of an appropriate place of the handle stem 30 and capable of transversely protruding out of the wall of the handle stem 30 for being correspondingly engaged in the plurality of engagement holes 221 of the handle tube 22.

[0022] The seat tube 51 extended upwards from a front end of the rear frame 5 of the electric scooter 1 has two projections 510 respectively disposed at two opposite sides of a top end of an inner surface of a wall thereof as well as a plurality of engagement holes 511 vertically arranged in the wall thereof. A clamp member 52 mounted to the top end of the seat tube 51.

[0023] The seat post 60 extended downwards from the seat 6 of the electric scooter 1 is capable of being inserted and engaged in the seat tube 51 of the rear frame 5 and has two grooves 600 respectively disposed at both sides of an outer surface of a wall thereof for corresponding in position to the two projections 510 of the seat tube 51. A resilient stopper 601 is accommodated in an interior of an appropriate place of the seat post 60 and capable of transversely protruding out of the wall of the seat post 60 for being correspondingly engaged in the plurality of engagement holes 511 of the handle tube 51.

[0024] In using, referring to FIGS. 1, 3 and 5, when the handle 3 or the seat 6 are to be adjusted in height, only to press the resilient stopper 301 of the handle stem 30 or the resilient stopper 601 of the seat post 60 to move the handle 3 or the seat 6 to a required height, and then make the resilient stopper 301 engaged in one of the engagement holes 221 of the handle tube 22 or make the resilient stopper 601 engaged in one of the engagement holes 511 of the seat tube 51, thus easily and conveniently adjusting and fixing the handle 3 or the seat 6 at a required position for people of different height to ride the electric scooter 1 comfortably.

[0025] The invention has the following advantages, as can be understood from the aforesaid description.

[0026] 1. The height-adjusting device of the present invention enables people of different height to adjust the handle 3 and the seat 6 of the electric scooter 1 easily and conveniently.

[0027] 2. The engagement between the projections 220 of the handle tube 22 and the grooves 300 of the handle stem 30 makes the handle stem 30 quickly and vertically moved within the handle tube 22 in a fixed direction without swiveling. Similarly, the engagement between the projections 510 of the seat tube 51 and the grooves 600 of the seat post 60 makes the seat post 60 quickly and vertically moved within the seat tube 51 in a fixed direction without swiveling.
